ID: Basic outline of frond is like the other two "Male"
ferns, with middle pinnae broadest, basal ones much smaller. Pinnae have a concave or crisped appearance. Scales on basal part of
stalk very pale brown or whitish (often even paler than those shown in the
bottom picture on this page). Does not have dark spot at base of
pinna like Scaly Male Fern. Growth habit very distinctive, with
crowns in groups of several close together.

Other features: Sori often only 1-2 per pinnule, but can be
up to 6 on the larger pinnules. Has whitish scales scattered on
backs of pinnae and rachis, but rachis not densely clothed with scales
like Scaly Male Fern.
